Embodiment Construction

[0021]FIG. 1 is a diagram illustrating a structure of a data rewriting system using a data rewriting apparatus according to a first embodiment of the present invention. The data rewriting system comprises a camera 1, a camera accessory 2 and a PC 3, and these component apparatuses are signal-connected by communication lines 4 and 5.

[0022] In this embodiment, the camera 1 is a subordinate concept of “data rewriting apparatus”, the camera accessory 2 is a subordinate concept of “peripheral device”, and the PC 3 is a subordinate concept of “host computer”. Further, the communication lines 4 and 5 are paths which are widely used for transmission / reception of information. The communications are not limited to cable communications using conductive lines and optical fibers and the like, but include radio communications using light, acoustic waves and radio waves, etc.

[0023] The camera 1 includes communication means 9, input means 10, data update means 11, identifying information storage ...
